Friction Loss in Turbine Water Power System. Water is stored in an elevated reservoir. To generate power, water flows from this reservoir down through a large conduit to a turbine and then through a similar-sized conduit. At a point in the conduit 89.5 m above the turbine, the pressure is 172.4 kPa and at a level 5 m below the turbine, the pressure is 89.6 kPa. The water flow rate is 0.800 m/s. The output of the shaft of the turbine is 658 kW. The water density is 1000 kg/m. If the efficiency of the turbine in converting the mechanical energy given up by the fluid to the turbine shaft is 89% (n, = 0.89), calculate the friction loss in the turbine in J/kg. Note that in the mechanical-energy-balance equation, the W, is equal to the output of the shaft of the turbine over 7,. %3D

reservoir. To generate power, water flows from this reservoir down through a
large conduit to a turbine and then through a similar-sized conduit. At a point
in the conduit 89.5 m above the turbine, the pressure is 172.4 kPa and at a level

energy given up by the fluid to the turbine shaft is 89% (n. = 0.89), calculate the
friction loss in the turbine in J/kg. Note that in the mechanical-energy-balance
equation, the W, is equal to the output of the shaft of the turbine over 7,.
